A Study to Assess the Effect of Rho-Kinase Inhibitor AR-12286 Ophthalmic Solution 0.5% and 0.7% in Patients With Chronic Angle-closure Glaucoma

Phase 2

• Conditions: Chronic Angle-closure Glaucoma
• Interventions: Drug: Rho-Kinase Inhibitor

• Registration Number: NCT02152774
• Lead Sponsor: New York Glaucoma Research Institute

Brief Summary

To evaluate the ocular hypotensive efficacy of Rho kinase Inhibitor (AR-12286 0.5% and 0.7%) ophthalmic solutions in patients diagnosed with chronic angle-closure glaucoma treated for 6 months.

Secondary Outcome

Secondary objectives are:

1. To evaluate the early effect of Rho kinase Inhibitor (AR-12286) in reducing intraocular pressure (IOP).

2. To evaluate the long term effect of the drug on IOP.

3. To determine if AR-12286 can be used as directed therapy for CACG, reducing or eliminating the structural blockage of the trabecular meshwork that leads to development of elevated IOP.

Arm && Interventions

Group	Intervention	Description
0.5% Rho-Kinase Inhibitor	Rho-Kinase Inhibitor	AR-12286 is a novel, potent Rho-kinase inhibitor developed by Aerie Pharmaceuticals, Inc., Bridgewater, NJ. It has single-digit nanomolar inhibitory activity against Rho-kinase in enzymatic inhibition assays. Mechanism-of action studies in monkeys demonstrate that AR-12286 lowers IOP primarily by increasing aqueous humor outflow through the trabecular meshwork Rho-kinase AR-12286 is well tolerated and produces clinically and statistically significant ocular hypotensive efficacy in patients with ocular hypertension and glaucoma. It is well tolerated by most patients and the only side effect was ocular hyperemia in a minority of subjects. It is currently in phase II testing.
